I am in the process of builking a fish room with over 100 tanks. I have 10s, 15s and 20 gallon long tanks that I will be putting on central filtration systems. I have access to all of the 3/4 inch marine plywood that I can use but I need to know what demensions that I should cut the plywood for the stands? I intend to set the tanks "at end" so that only their small side will show. Are there any members out there that can give me some guidience in this matter?
